"Light as a Feather, Stiff as a Board"
The basic premise of this game is to have one person lie on the floor while everyone else sits on their knees around her with both hands slightly under her. There is one "Storyteller" who sits by the head and tells a made up story about the person on the floor's life and her "untimely demise." At the end of the story, everyone chants "Light as a Feather, Stiff as a Board" repeatedly as they lift her off of the ground. The idea is to have everyone believing that "spirits" are helping to lift her off the ground (in reality, she is probably being lifted because of all the people helping to lift her). Take turns, and tell a story about everyone!

Murder
Put slips of paper into a hat (the number of papers should be the same as the number of guests). Have your guests each choose one slip of paper; they should not show it to anyone else. Each slip of paper will be blank with the exception of one that says "Murderer." The guest who picks "Murderer" has to walk around the party and "kill" people by winking at them. As soon as one of the guests is winked at, he/she has to count to three and then fall on the floor. If someone knows who the murderer is, they have to say "Stop! I know who the Murderer is." If the accuser is wrong, then he/she is "dead" and out of the game. If the accuser is correct, then the game is over, and he/she is the winner.
